I see no point in seeing an unnecessary flashback sequence since we got brief flashes and Cap told us all the pertinent information.

The reasoning behind your opinion makes no sense. Frequently superhero action cartoons tell stories such as this in one half hour episode.

The notion that all these episodes have to be stretched across multiple episodes is an argument the haters utilize to irrationally bash this show.

How did we not get the Avengers take on Hyperion? Cap found Hyperion suspicious and did not approve of his methods.

In Justice League, Captain Marvel/Shazam is introduced and a guest star in absolutely ONE episode. He's established, joins the Justice League, has a conflict with Superman, fights Superman, loses, and leaves the Justice League. All in ONE EPISODE. We never see Captain Marvel/Shazam show up and ever do anything meaningful again in the series. Episode must have been terrible and garbage. What about all the other Leaguer's take on Shazam? They could've spent five episodes building up the dissent between the Justice League and Captain Marvel only for it to have a big blowoff. Instead it all happened in JUST ONE EPISODE.
